[0018] Reference Figure 2The inner wall of the upper half of the round tower 16 is provided with a connecting block. The middle of the two connecting blocks is fixedly installed with the ceramic dust collector 15. The connecting block fixes the ceramic dust collector 15. The connecting block and the round tower 16 are fixed to stabilize the structure. The top of the ceramic dust collector 15 is fixedly installed with the conveying pipe. One end of the conveying pipe is bolted to the induced draft fan, and the other end of the conveying pipe is bolted to the steam heater. The gas is conveyed to the conveying pipe through the induced draft fan, and the tail gas is processed through the conveying pipe to achieve the effect of purifying the tail gas. The conveying pipe is connected to the steam heater to perform multiple purifications on the round tower 16. SO3 in the incineration flue gas combines with water vapor in the flue gas to generate sulfuric acid vapor. When the flue gas temperature is lower than the acid dew point temperature, the flue and equipment are prone to corrosion. Determining the acid dew point temperature of the flue gas from the incineration of hazardous waste can effectively avoid low-temperature corrosion.

The solution is transferred to the connecting pipe 2 8 through the delivery pipe 4, and the connecting pipe 2 8 then transports the solution to the annular pipe 2 9. The solution flows on the inner wall of the annular pipe 2 9. , and then spray it out through the spray pipe 2 10, and transport the solution to the annular pipe 3 13 through the connecting pipe 3 12. The solution flows along the inner wall of the annular pipe 3 13, and is sprayed out through the spray pipe 3 14, thereby achieving the effect of multiple purification of acidic gas, effectively preventing the re-synthesis of dioxins, and the gas enters the filter layer to adsorb heavy metals, passes through the filter layer to enter the packing layer, and lime and activated carbon are placed in the packing layer. The purification effect of lime and activated carbon is better. The ceramic dust collector 15 is turned on to absorb the exhaust substances, and the gas rises into the transmission pipe. Finally, the induced draft fan is turned on, and the gas is transmitted to the transmission pipe through the induced draft fan, and the exhaust gas is treated through the transmission pipe to achieve the effect of purifying the exhaust gas.
